[Maximal and high-velocity power. A study in Swiss male and female national ski athletes].

An important quality aspect of a good alpine skier is his ability to produce torque at high angular velocities. Both the isokinetic dynamometer (Cybex 6000, open chain of movement) and a device to measure flight time in skill jumps (Ergo Jump, closed chain of movement) allow to identify subjects with outstanding capacities in explosive force production and possibly to measure changes after specific training protocols aiming at improving this important characteristics of alpine skiers.
